This is an email I sent today to developers who work with me, it is exactly as I wrote it except for project and developer names which I’ve redacted.Dear Developers,S asked me a difficult question today, and I think the answer (which took me a few minutes to arrive at) is worth sharing with all developers, mainly because many of you will surely face the exact same problem especially in [maintenance and enhancement] projects.By now I think it is crystal clear that one of our non-negotiable requirements for coding is that we write unit tests.For new projects it is easy – in fact fo...

In this rapidly evolving IT world, quality has become the primary parameter to achieve a niche position. The IT professionals are using an array of advanced software testing tools to ensure an excellent quality of the application.And among this set of highly sophisticated software testing tools and techniques, web browser has emerged as one of the simplest, nicest and affordable means which can be easily used, even on a daily basis for testing life cycle of the application.In fact, there is huge number of testers who use and test the application on Firefox browser, since being an open source b...

There is a question on Stackoverflow which says "How deep are your unit tests?". It is asked by a guy named John Nolan. The question is not too new, but what catches me is the Best Answer given by Kent Beck, who is the creator of Extreme programming(XP) and Test Driven Development(TDD).Let's look at the question first.The thing I've found about TDD is that its takes time to get your tests set up and being naturally lazy I always want to write as little code as possible. The first thing I seem do is test my constructor has set all the properties but is this overkill?My question is to what level...

We do several kinds of testing. Some specifics:For our PHP code, we have a suite of a few thousand test classes using the PHPUnit framework. They range in complexity from simple true unit tests to large-scale integration tests that hit our production backend services. The PHPUnit tests are run both by developers as part of their workflow and continuously by an automated test runner on dedicated hardware. Our developer tools automatically use code coverage data to run tests that cover the outstanding edits in a developer sandbox, and a report of test results is automatically included in our cod...

I pointed out to someone at work today that PyDev 2.5.0 now offers really cool TDD support. I’m not a huge TDD proponent or anything, but this stirred up a discussion. This guy, let’s call him John, said that â€œTDD may shorten the time it takes to develop a feature, but sometimes a feature is so urgent we may want to deliver it as quickly as possible and test it later”.Sentences like that make me weep.I tried to explain that without testing, the risk of releasing a piece of code is unimaginable. As important as a feature may be, the product might be...

Usually, The purposes of log are for troubleshooting and displaying program running status. Good log will help us locate the error easier. Many programmers think log in programs is very simple, but it's not an easy task to write log codes to efficiently locate the error. Here we discuss about program log in three aspects:Where to logWhat to logLog styles to be avoidedWhere to log1. When calling external functionsWhen your program is calling some external functions which are not written by you, you need to log before and after the external function call. This will help debug.1. LOG.debug("Call...

When developers first discover the wonders of test-driven development, it’s like gaining entrance to a new and better world with less stress and insecurity. It truly is a wonderful experience well worth celebrating. But internalizing the benefits of testing is only the first step to enlightenment. Knowing what not to test is the harder part of the lesson. While as a beginner you shouldn’t worry much about what not to test on day one, you better start picking it up by day two. Humans are creatures of habit, and if you start forming bad habits of over-testing early on, it will be h...
